Final answer:
When approaching a railroad crossing, drivers should look and listen for trains, never stop on the tracks, and wait for the train to pass completely. At a regular intersection, drivers should follow traffic signs and signals.
Step-by-step explanation:
When approaching a railroad crossing, there are several differences in how a driver should approach it compared to a regular intersection. First, at a railroad crossing, it is crucial to always look and listen for approaching trains. This is because trains take longer to stop than cars, and if a train is coming, the driver must come to a complete stop before the crossing. In contrast, at a regular intersection, a driver needs to follow traffic signs and signals, and yield the right-of-way if necessary.
Another difference is that at a railroad crossing, it is important to never stop on the tracks. This is because stopping on the tracks can lead to a vehicle getting stuck or hit by a train. In addition, if a driver sees flashing lights, a lowered gate, or hears a train horn at a railroad crossing, they should always wait for the train to pass completely before proceeding. At a regular intersection, there are no such flashing lights or gates, so drivers can proceed when it is safe and their turn to go.
